ALBERT W. CAMPBELL, OF HARTFORD, CONNECTICUT.

SNO'W GUARD.

Application filed June 25, 1924..

Y '0 all whom it may concem:

Be it known that I, Amnnrr W. CJiAIlPBIiLL, a citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented a new and useful Improvement in Snow Guards, of which the following is a specification.

This invention relates to those articles which are designed to be applied to the roofs of houses and other buildings that are covered with slate, tile or shingles, for the purpose of retaining and breaking up snow and ice and preventing such from sliding off in heavy masses and causing damage.

The object of the invention is to provide a strong, durable, cheap and attractive article of this nature that can be quickly placed and firmly held in position on such roofs, which article is formed to shape without the use of rivets or solder and which is so'designed that it will not be bent out of shape and become useless by the pressure and force of snow and ice.

This object is attained by bending and folding together pieces cut or stamped from Sheet metal in such manner that when assembled the base portions of the articlesn'iay be readily slid under the overlapping sections of slate, tile or shingles and hooked over the edges of the underlying sections on which they lie, with the foot portions extending upwardly. which foot. portions are so designed and folded into the web portions that they brace tl'iemiselvcs in all. directions against any pressure or force that the snow and ice may exert.

In the accompanying drawings Fig. 1 shows an elevation looking toward the upper face of the guard. Fig. 2 shows a plan view of the guard. Fig. 3 shows an elevation looking toward the lower face of the guard. Fig. 1 shows a side view of the guard. Fig. 5 is a central longitudinal section. Fig. 6 is a developed plan of one of the strips from which the foot of the guard is folded. Fig. 7 is a similar view of one of the strips from which the web of the guard is folded. Fig. 8 is a view of one end of the base piece of the guard. Fig. 9 is a view of the foot piece partly folded. Fig. 10 is the partly folded web.

The embodiment of the invention illustrated is composed of three strips of metal 1, 2 and 8, preferably copper, of substantially the same width that are folded together so as to firmly interlock and brace each other.

Serial No. 722,255. "2

The base piece 1 at the upper end is slitted and a portion turned down to form a hook 4 that is designed to be pushed under the lower edge of an overlying section of a slate, tile or shingle and be hooked over the upper edge of the underlying section of slate, tile or shingle upon which the guard is to rest. Near the lower end the base piece is slightly reduced in width and is 1 rovided with a slot which is to be utilized for the purpose hereinafter mentioned. The lower end of the base piece is also provided with tongues 6 which are to be folded over the other pieces, as will subsequeu ty appear.

The ends 7 of the foot piece are first bent forward at right angles, on the lines 8 and then the strip is doubled backward on the lines 9 until the ends come together, thus producing a T-shaped piece as shown in Fig. 9.

The web piece 8 is doubled on the middle line 10, and the ends folded out at right angles on the lines 11, forming the inverted T-shaped piece shown in Fig. 10. The sections 7 of the foot piece 2 are thrust edgewise between the sections 12 of the web piece 3 and then the outer corner of the web comprising both the doubled sections 12 of the web piece and the inserted sections 7 of the foot piece, is bent over on a diagonal line 13. This folds both pieces on the lines 13 (Figs. 6 and 7) and interlocks them, producing a very stilt substantially triangular web 14 formed of eight thicknesses of metal, back of the foot piece and extending longitudinally with relation to the base piece to which the parts are substantially attached. hen in this condition the upper corners of the folds 9 of the foot piece are bent back on lines 15 (Fig. 6) so as to form triangular sections 16 the edges of which bear against the web.- This stilfens the upstanding portion of the foot and braces the web on each side besides interlocking the pieces more firmly.

With the foot and web pieces assembled in this manner the ends 17 of the web piece are set upon the reduced end 18 of the base section and bent around under it and the tongues 19 at the end of the web piece are tucked up through the slot 5 in the base piece, after which the tongue 6 at the end of the base piece are folded on lines 20 (Fig. 8) over onto the top of the sections 17 of the web piece near the web.

The width of the strip from which the foot is formed is such that the bottom edge of the foot, when the base piece is slipped under an overlying slate, tile or shinglerests upon the slate, tile orshingle so that the foot cannot bend sidewise. The upper corners 16 of the foot being bent down against the web also prevent the foot piece from being bent sidewise as well. as backward, and at the same time they prevent the web from being bent sidewise, while the web braces the foot'and prevents it from being bent downward. By bending and folding the strips together in the manner described, without the employment of solder or the use of rivets, a very strong, durable and eflicient snow guard, which is easily installed in place of use, is produced at a minimum cost.

The invention claimed is:

1. A snow guard formed of strips of metal comprising a base, a web extending upward lengthwise of the base and having portions folded about the base for securing the parts together, and a foot extending transversely of the base and web and having a part inserted between and folded over with portions of the web whereby said parts are interlocked and support each other against the s rains of use.

2. A snow guard formed of strips of-metall comprising a base, a web extending upward lengthwise of the base and having portions folded about the base for securing the parts together, and a foot extending transversely of the base and web andhaving a part inserted between and folded over with portions of the web and parts bent back against the web.

A snow guard formed of strips of metal comprising a base having a slotted section, a Web extending upward lengthwise of the base and'having portions folded around the slotted section and tucked up through the slot for securing the parts together, and a foot extendingtransversely of the base and Weband-having a part inserted between and f lded over with portions of the web.

t. A snow guard formed'of strips of metal comprising a base, a web extending upward lengthwise of the base and having portions tolded around the base with portions-of the base bent over portions of the web forinterlocking the base and web together, and a foot extendingtransversely of the base and web and having a part inserted between and fo ded over with portions of the web. I

5. A snow guard formed of three-strips of metal comprising a base, a web extending upward lengthwise of the base andhaving a portion folded about'the base, and a foot extending transversely of the base and web and havinga portion folded'about the web, said folds-interlocking the strips and causing them to support each other against the strains of use.
